Procedural Landscape Shader

This is a procedural landscape shader designed for Blender 4.1's Cycles rendering engine. The shader generates terrain procedurally, meaning landscapes are created algorithmically rather than from pre-made models or textures. Note that the generated terrain cannot be converted to mesh geometry directly; if you need to export terrain for use in other applications or workflows, you'll want to use an accompanying terrain generator tool mentioned in the course materials.
